摘要： This invention relates to the industrial fishing and can be used for catching fish using trawls. This invention relates to the improvement of the operational properties of a trawl by method of evenly distributing loads in the netting fabric and prolonging operational time of the trawl. Herein described trawl for catching fish is comprised of netting and cable panels. Cable panels are forming the mouth part. The novelty of described invention is that two or more trapeze-shaped netting panels of even dimensions are connected to each of the cable panels, also tangent of the angle of the displacement of the lateral side to its longitudinal axis of each netting panel is determined by a formula.

摘要： Netting (15) includes mesh bars (26) made from twines (11,13) which possess physical properties that vary, change or alternate along a series of collinear mesh bars (26). The non-homogeneous media obtained by arranging in this way mesh bars (26) having varying physical properties may be configured to dampen or attenuate vibrations in the netting (15) such as harmonic oscillations (resonance). Furthermore, twines (11, 13) that attenuate vibrations may be chosen that also reduce the amount of material required to make netting (15) which has strength similar to or greater than conventional machine-made netting (15). Due to reduced vibration, the improved netting (15) lasts longer than conventional machine-made netting (15), and reduces the possibility of injury to fish which escape through a trawl's mesh cell openings.

摘要： By a trawl door (1) with a principally rectangular, preferably angularly shaped plate (2) and with adjustable hatches for adjusting the active surface areas of the trawl door the adjustable hatches have been placed at each side of a central longitudinal axis of the plate (2), a smallest hatch (10) being positioned at the middle of the lowermost portion (6) of the plate (2) in operation, and a hatch (18) with a size of about the double being positioned at the middle of the upper portion (4) of the plate (2). Hereby an almost universal trawl door is obtained which can easily be readjusted for almost any thinkable fishery, since the trawl door (1) with completely closed hatches (10, 18) gives a maximal spreading and a minimal spreading by completely open hatches.

The trawl door (10) includes at least one main deflector (24, 25) having a profile (46) formed by an inner surface (48) and an outer surface (47). The profile (46) spans a chord length "C" that extends along a Chord Direction Line (83) between leading and trailing edges (12, 14) of the main deflector (24, 25). The trawl door also includes at least one leading edge slat (20, 22) at least a portion of which is located in front of the outer surface (47) of the main deflector. The trawl door (10) in one aspect is characterized by an acute angle of inclination (91, 92) between a chord line (81, 82) of the leading edge slat (20, 22) and the Chord Direction Line (83) that is at least thirty-five degrees (35°). The trawl door (10) in another aspect is characterized by having an aspect ratio of at least two to one (2.0 : 1.0).
